As residents living in hazard-prone areas face on-going environmental threats, the actions they take to mitigate such risks are likely motivated by various factors. Whereas risk perception has been considered a key determinant of related behavioral responses, little is known about how risk mitigation actions influence subsequent perceived risk. In other words, do actions to prevent or mitigate risk reduce risk perception? This longitudinal study considers the dynamic relationships between risk perception and risk-mitigating behavior in the context of forest disturbance in north-central Colorado. Based on panel survey data collected in 2007 and 2018, the results provide a first look at changes in perceived forest risks as they relate to individual and community actions in response to an extensive mountain pine beetle outbreak. Analysis revealed that the perception of direct forest risks (forest fire and falling trees) increased, whereas indirect forest risk perception (concern on broader threats to local community) decreased across the two study phases. Higher individual or community activeness (level of actions) was associated with subsequent reductions in perceived forest fire risk, smaller increases in direct risk perception, and larger decreases in indirect risk perception. These findings contribute insights into the complex risk reappraisal process in forest hazard contexts, with direct implications for risk communication and management strategies.  相似文献

Subsidies to residential utility customers are important in‐kind transfer mechanisms in developing countries. Do these subsidies reach the poor? This article finds the average targeting performance of water and electricity subsidies to be similar to that of other social‐transfer mechanisms using the same targeting method. The most common form — a quantity‐based consumption subsidy aiming to subsidise low‐volume customers — is highly regressive. Many geographically‐targeted and most means‐tested utility subsidies are progressive, but still exclude many poor households. Connection subsidies are an attractive alternative in low coverage areas, but they will only reach the poor if utilities extend network access to poor households and if households choose to connect.  相似文献

Defining the poverty line has been acknowledged as being highly variable by the majority of published literature. Despite long discussions and successes, poverty line has a number of problems due to its arbitrary nature. This paper proposes three measurements of poverty lines using membership functions based on fuzzy set theory. The three membership functions, namely exponential, trapezoidal and quadratic sigmoid together with their calculation steps are discussed. Average monthly household incomes of Malaysians are used to illustrate the proposed poverty line. Three new sets of poverty lines were derived for 3 years as numerical application to the proposed membership functions. The numerical results show the flexibility of poverty lines resulted from the composition of the proposed functions. It suggests that the official poverty line for Malaysians is too low thus creating an underestimation of the extent of poverty in Malaysia.  相似文献

This article examines African American folklorist Zora Neale Hurston’s book-length biography and film of the last known Middle Passage survivor, Oluale Kossola/Cudjo Lewis, to explore her cinematic and literary engagement with slavery and to recover Lewis as a co-author of both documents. Hurston’s literary project, ‘Barracoon’, in which she situated herself merely as Kossola’s amanuensis and foregrounded the ‘inexpressible violence’ and ‘horror’ of his experience, represented an unusually frank twentieth-century record of enslavement and post-slavery life. Such work pre-dated and lacked the patronising tone of much of the WPA Slave Narrative Collection (1936–1938), whose investigators were mainly white and whose subjects’ accounts were often reconstructed loosely from field notes. Moreover, Hurston’s footage of Lewis circumvented literary mediation altogether to provide an Atlantic slavery survivor with an unprecedented visual outlet for self-expression.  相似文献

This article concerns gender and feeling real. Beginning with Judith Butler’s deconstruction of gender as an ontological category, it argues that the subjective experience of gender as real has been underaccounted for. By reviewing Butler’s work on gender melancholy and then elaborating psychoanalytic theories of identification and reality, this article links feeling real to the dual capacities to both separate from and connect with the object. To illustrate the implications for thinking gender identity and transformation, it concludes with a reading of Miles Walser’s poem about the name discarded in a gender transition.  相似文献

Despite growing interest in the use of evidence-based treatment practices, adoption of pharmacotherapies for treating substance use disorders (SUDs) remains modest. Using data from telephone interviews with 250 administrators of publicly funded SUD treatment programs, this study estimated a model of adoption of medication assisted treatment (MAT) for SUDs and examined the relative importance of regulatory, cultural, medical resource, patient-level, and funding barriers to MAT implementation. MAT-adopting programs had significantly greater medical resources, as measured by the employment of physicians and nurses, than non-adopting programs. Administrators of non-adopting programs were asked to rate the importance of 18 barriers to MAT implementation. The most strongly endorsed barriers were regulatory prohibitions due to the program's lack of medical staff, funding barriers to implementing MAT, and lack of access to medical personnel with expertise in delivering MAT. Barriers related to insufficient information about MAT and unsupportive staff attitudes were not widely endorsed. These findings suggest that efforts to promote the implementation of MAT that are inattentive to funding barriers and weaknesses in medical infrastructure may achieve sub-optimal results.  相似文献

This paper is derived from an interest in the development of automated approaches to tackle examination timetabling problems effectively. We propose a hybrid approach that incorporates effective heuristic operators within the great deluge algorithm. The latter was chosen because of consistently good performances being reported within the examination timetabling research domain. The additional heuristic procedures further enhance the overall effectiveness of this integrated hybrid approach. These procedures are drawn from methodologies that have appeared in the literature under term the “electromagnetic-like mechanism”. The aim is to move sample points towards a high quality solution while avoiding local optima by utilising a calculated force value. This value, which is calculated dynamically, is treated as a decay rate in determining the level within the great deluge algorithm. To evaluate the proposed algorithm, we carry out experimental work on two types of examination timetabling datasets. All the related results and analysis obtained illustrate that this hybrid approach is effective when compared with existing approaches in the literature.  相似文献
